A combined gene set enrichment analyses (GSEA) of all GCT cell lines (TCam‐2, 2102EP, JAR, and GCT72) co‐cultured with TM cells HUVEC, JURKAT, THP‐1‐MIL4/IL13, and HVHF2 compared with mono‐cultures indicated that processes like ‘extracellular matrix organization’ and ‘integrin cell surface interaction’ were among the top significantly deregulated gene sets (Fig. 2B). The gene discussed is IL13; the disease is granular cell tumor.
